The present study addresses the critical problem of remediation crude oil leachate, which is generated through leaching highly recalcitrant and solubilized fractions from petroleum hydrocarbon-contaminated sites presents a significant environmental hazard. leachate used in this showed BOD/COD ratio 0.14, indicating high dominance fraction. Eight bacterial strains were selected based on their ability to solubilize degrade leachate. isolates biosurfactant production 0.04–0.73% facilitated solubilization, biodegradation 43.95–87.91%. Bacillus licheniformis highest degradation as well among all. consortium all 8 was then optimize improve performance. Maximum 65.19% obtained at pH 7, 30 °C 1% inoculum concentration. First-order kinetic modeling that specific rate (k) 0.16/day 5% reduced 0.05/day 25% concentration, representing inhibitory action effectiveness also analyzed leachate-contaminated soil microcosm. Phytoremediation using Typha latifolia microbe-assisted phytoremediation served complementary treatment approaches. maximum 86.86% observed by phytoremediation, synergistic both plants microbes GC-FID analysis confirmed reduction components different bioremediation treatments, while there minimal change control set. microbial revealed increase total count proportion degrading bacteria treatments compared with 2.8 fold 27.6% for success bioremediation. remediated samples very low or no mutagenic risk set Ames test, method.

The present study aimed to comprehensively dissect the petroleum hydrocarbon degradation mechanism of Acinetobacter vivianii KJ-1. isolated and identified strain was able proliferate using diesel as sole carbonaceous substrate. Via comparative genomics, an in-depth analysis performed elucidate genome similarities disparities between this related strains, thereby uncovering a core well genes with uncharacterized functions. Transcriptome analysis, carried out under different substrate conditions (C16, diesel, sodium acetate) manifested distinct gene expression modalities. A multitude associated alkane metabolism were differentially expressed, among which alkB1_1 alkB1_2 conspicuously upregulated. Prokaryotic implemented, enzyme activity recombinant protein peaked at pH level approximately 7.0 within temperature range 30 40 °C. shown possess ability degrade n-hexadecane. Collectively, research not only augments understanding A. KJ-1 but also provides fundamental basis for developing bioremediation strategies targeting hydrocarbon-contaminated environments.

Petroleum refinery effluents (PRE) are a significant cause of pollution. It contains toxic compounds such as total petroleum hydrocarbons (TPH), and polycyclic aromatic (PAHs), well heavy metals. They show huge threat facing the aquaculture habitats, human health, environment if they not treated before discharging into environment. Physical chemical procedures used to treat hydrocarbon pollution in PRE, but these techniques often result formation hazardous by-products during remediation process. However, PRE various microbial communities, including bacteria, yeast, microalgae, fungi. The bioremediation biodegradation oil contaminants primary functions communities. microorganisms can perform additional limited metals removal, production biosurfactants, nitrogen fixation. This review contributes comprehension natural communities their complex effluents. Understanding would facilitate advancement innovative biotechnology aimed at treating improving processes, potentially transforming valuable bio-products. Moreover, it assists determining most effective bioaugmentation strategy enhance PRE. highlights potential for sustainable green approaches using replace therapies expensive physical treatments future.
